英文:
Autostart `slurmd` service on computes after reboot
问题
我正在调用 scontrol reboot <nodename> 重启我 SLURM 集群中的计算节点。
通常情况下，重启会超时（从 SLURM 角度来看），并且节点状态设置为 "DOWN"。
（RESUME_TIMEOUT 设置为 300）。
这可能是因为 slurmd 服务在引导后未自动启动。
默认情况下，该服务是 "disabled"：
[root@c1 ~]# systemctl status slurmd
● slurmd.service - Slurm node daemon
Loaded: loaded (/usr/lib/systemd/system/slurmd.service; disabled; vendor preset: disabled)
Active: inactive (dead)
使用 systemctl enable slurmd 激活它在下次重启后不会持续，服务仍然会再次变为 "disabled"。
我认为这是因为更改没有在用于引导的镜像中发生。
如何在计算节点上启用 slurmd 服务，以便它在引导时自动启动并且 scontrol reboot 起作用？
英文:
I am calling scontrol reboot <nodename> to reboot compute nodes in my SLURM cluster.
The reboot usually times out (seen from SLURM) and the node is set to state "DOWN".
(RESUME_TIMEOUT is set to 300).
This presumably happens because the slurmd service does not autostart itself after boot.
By default, the service is "disabled":
[root@c1 ~]# systemctl status slurmd
● slurmd.service - Slurm node daemon
Loaded: loaded (/usr/lib/systemd/system/slurmd.service; disabled; vendor preset: disabled)
Active: inactive (dead)
Activating it using systemctl enable slurmd does not last after the next reboot, the service is again "disabled" then.
I assume this is because the change does not happen in the image which is used for booting.
How can I enable the slurmd service on the computes so that it starts on boot and scontrol reboot works?

这可能不是推荐的方式，但我在工作中设置了一个小集群，并且我修复它的方法是使用一个cron作业：
@reboot /usr/bin/scontrol update nodename=[在这里输入主机名] state=resume
英文:
This is probably not the recommended way, but I setup a mini cluster at work and the way I fixed it was with a cronjob:
@reboot /usr/bin/scontrol update nodename=[put hostname here] state=resume

我通过OpenHPC邮件列表收到了Antanas Budriūnas的回复，解决了这个问题。
（在主节点上执行）
chroot ////
systemctl enable slurmd
exit
英文:
I got a reply from Antanas Budriūnas via the OpenHPC mailing list which solved the issue.
(execute on master node)
# chroot /<path>/<to>/<cnode>/<image>
# systemctl enable slurmd
# exit
